Hear T-Pain Sing An Entire Concert For Fans Without Auto-Tune

For those who think artists' use of pitch-correcting software Auto-Tune is meant only for those who are unable to sing well, T-Pain is here to offer you proof why that's not necessarily true.
Here he was this week, unplugged, singing a few of his hits including "Buy U A Drank" and "Up Down", plus some new songs, for NPR's Tiny Desk Concerts series.

It's worth listening to. Click below, and of course comment. Should he make an entire album this way, or should he stick with his signature Auto-Tuned sound?
